How many amp hour battery? How long are they guaranteed for?
41597
Hi, Dakota. Each battery assembly half is rated at 9 amp hours so the unit is a total of 18 amp hours. I think the warranty is two years. I have had mine in service for over a year and a half and it still charges up to full original capacity.

IIRC, the capacity is 9 ampere-hours, but I do not recall the warranty period. Sorry.

The lady told me it was guaranteed for one year. If you're gong to buy one of these replacements, be sure to note the way the battery jumper is placed on the original battery because there are no instructions that come with the two batteries that comprise the replacement set. Otherwise, just look up the on-line videos you can find on YouTube that explain. It's simple, and it's pretty clear just from how they place the double-stick tape that binds the two batteries together. I don't know why the folks at this company don't send out a simple set of instructions; but they don't.

Yes. Fully charged, the battery box holds a 60 amp-hour charge @ 12VDC or 6 amp-hour @ 120VAC. If your amplifiers consume 250W @ 120VAC, thats a little over 2 amps x 2 = 4 amps x 12 minutes = 48 amp-minutes or 0.8 amp-hour. Theoretically your amplifiers will work for 7.5 hours. Realistically, something less than 7.5 hours, because of line loss, resistive heating, battery age, etc.

I've run mine for over 2 hours but never until the battery ran out. I hope that helps.

I think I did a three hour gig on batteries with no problem. Since then I just run it on the transformers to be safe. But I suspect they will go for much longer on batteries than I tried.

I've used mine for several hours. I havent timed it but I've been very happy with my purchase. They will also provide a light beep to let you know before they die to plug them in.

I've had these batteries for almost a year. I have two pair so that I can switch out the used with freshly charged and immediately put the used on the charger. Because I have a spare pair (which I HIGHLY recommend) I don't pay close attention to the exact time but I would say it generally is about 2 hours when I go back and they are completely charged. A second pair is very affordable and you are always assured that you will have a fresh pair when needed. I got a second pair as many reviewers said these batteries were unreliable and die after a couple of uses. I have had none of those problems. If you need a more precise time, I will be happy to check that for you. I've had these batteries for almost a year.

You can still buy brand new replacement batteries for these for about $75. On a new battery, this machine will run 3-4 hours on a single charge. When the battery gets old, as in any laptop, it won't hold for more than a few minutes. But that has nothing to do with this particular model of computer. That is true of any computer and any rechargeable battery system. Depending on which one you get, you might get 30 minutes or 3 hours of batter life. It's impossible to know. Ask the seller. If the batter is less than a year old, you will get very good battery life out of it ... at least 2 hours.

I actually plug them in to charge and forget it. But I would guess an hour or two would be sufficient.

They only draw 200 mAMPS (0.0000002 amps) so the wattage is really insignificant if you are worried about battery life. I am in road construction and normally leave mine running for 5-6 hours and have never had a problem. FYI: I run these at the same time I am running my overhead light (strobe) and four corner strobes.

The battery in these packs are sealed lead acid AGM (absorbed glass mat). I've replaced the battery in another unit and it wasn't that hard. If you have the pack that looks exactly like the one in the picture here, it's battery is 3.875W X 5.875L X 3.75 H and is rated as 18 amp-hour. With that info you can go to dealers like "Battery plus" or "batteryspec.com" and match up another. When I changed out the battery in another unit, I added some padding as was on the original which cushion the battery keeping it from rubbing on the housing as it's carried or rattling slightly. The battery alone should only cost ~1/2 the price of a whole new pack, so it will save you some (but cost you the time to do it).

About an hour with regular batteries, 2+ hours with Energizer Lithium Max. The rechargeable batteries don't last long at all because they only start out at about 1.2 volts.

Amp hours are a measure of power. Theoretically, the battery should provide 125 amps for one hour at the stated 12 volts. However, at this high a current, I wouldn't count on it. More realistically, the battery should provide 10 amps at 12 volts for 12.5 hours or 20 amps for 6.25 hours...and so on and so forth. My experience is limited because I use them (two of them) along with an inverter to run a refrigerator and a few other pieces of equipment in a back up mode. They have done great when I've needed them!

Batteries are rated in mAh or milliAmpHours. AA batteries are normally 1500 mAh. This means you can draw 1500mA for an hour or 1.5 Amps for an hour (just removing the milli by multiplying by 1000).If you are drawing 2Amps this would last for 1.5Ah/2A this leaves you with 1.5/2 hours or .75 hours or 45 minutes.

Do you mean how many years before it needs to be replaced? Or, how long on a given charge? If years, I don't know but it should last longer than any lead acid battery. If you mean on a single charge, I haven't timed it but probably about 30-45 minutes for each battery (there are two).

40min to 1 hrs - depends on what refurbished quality battery is given by the seller.

A hour or two. Very worthwhile. The price is cheap enough to have sufficient power to do the job. Don't plan on a quick recharge. Just have enough for the job. If the job is very long. You can recharge while the other batteries are working.

Leon, I've had mine go for 3 full days with intermittent use maybe 3 to 4 hours a day, before I've become afraid they are going to be dead and charged them.
